The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

Explanationists about epistemic justification hold that justification depends upon explanatory considerations. After a bit of a lull, there has recently been a resurgence of defenses of such views. Despite the plausibility of these defenses, explanationism still faces challenges. Recently, T. Ryan Byerly and Kraig Martin have argued that explanationist views fail to provide either necessary or sufficient conditions for epistemic justification. I argue that Byerly and Martin are mistaken on both accounts.

We argue that explanationist views in epistemology continue to face persistent challenges to both their necessity and their sufficiency. This is so despite arguments offered by Kevin McCain in a paper recently published in this journal which attempt to show otherwise. We highlight ways in which McCain’s attempted solutions to problems we had previously raised go awry, while also presenting a novel challenge for all contemporary explanationist views.

Explanationism is a plausible view of epistemic justification according to which justification is a matter of explanatory considerations. Despite its plausibility, explanationism is not without its critics. In a recent issue of this journal T. Ryan Byerly and Kraig Martin have charged that explanationism fails to provide necessary or sufficient conditions for epistemic justification. In this article I examine Byerly and Martin’s arguments and explain where they go wrong.

Kevin Lynch's books are the classic underpinnings of modern urban planning and design, yet they are only a part of his rich legacy of ideas about human purposes and values in built form. City Sense and City Design brings together Lynch's remaining work, including professional design and planning projects that show how he translated many of his ideas and theories into practice. An invaluable sourcebook of design knowledge, City Sense and City Design completes the record of one of the (...) foremost environmental design theorists of our time and leads to a deeper understanding of his distinctively humanistic philosophy. The editors, both former students of Lynch, provide a cogent summary of his career and of the role he played in shaping and transforming the American urban design profession during the 1950s, the 1960s, and the 1970s. Each of the seven thematic groupings of writings and projects that follow begins with a short introduction explaining their content and their background. The essays in part I focus on the premises of Lynch's work: his novel reading of large-scale built environments and the notion that the design of an urban landscape should be as meaningful and intimate as the natural landscape. In part II, excerpts from Lynch's travel journals reveal his early ideas on how people perceive and interpret their surroundings—ideas that culminated in his seminal work, The Image of the City. This part of the book also presents Lynch's experiments with children and his assessment of environmental-perception research. The examples of both small-scale and large-scale analysis of visual form in part III are followed by three parts on city design. These include Lynch's more theoretical works on complex planning decisions involving both functional (spatial and structural organization) and normative (how the city works in human terms) approaches, articles discussing the principles that guided Lynch's teaching and practice of city design, and descriptions of Lynch's own projects in the Boston area and elsewhere. The book concludes with essays written late in Lynch's career, fantasy pieces describing utopias and offering new design freedoms and scenarios warning of horrifying "cacotopias.". (shrink)

According to the most important objection to the existence of moral beauty, true judgements of moral beauty are not possible as moral judgements require being motivated to act in line with the moral judgement made, and judgements of beauty require not being motivated to act in any way. Here, I clarify the argument underlying the objection, and show that it does not show that moral beauty does not exist. I present two responses: namely, that the beauty of moral beauty does (...) not lie in the moral goodness per se (the “adjacent properties” response); and that only a dispositional motivation to act is required for the moral judgements that are typically made as part of judgements of moral beauty, whereas aesthetic judgements only rule out state motivations to act (the “equivocation of motivation required” response). In addressing the objection, I show how moral beauty is consistent with disinterestedness, and so should be accepted more widely; and also clarify where the beauty in moral beauty resides, and how the moral-aesthetic distinction should be drawn.

Does religious belief differ in any interesting way from other kinds of belief? For now, take ‘belief’ to mean how one takes the world to be, on the basis of which they act. Call beliefs like this ‘ordinary beliefs’. There are also more complicated, or abstract, beliefs. Call such beliefs ‘non-ordinary beliefs’. Are religious beliefs different in any significant or interesting way from what we call ‘standard belief’? Our analysis shows that they are not. Although the content of religious belief (...) is different, and sometimes so is the function, religious beliefs are still mental, dispositional attitudes that aim to provide a correct representation of the world. Therefore, religious beliefs are best understood as a sub-category of standard beliefs, alongside ordinary and non-ordinary beliefs. This account of religious belief provides further insight into the meaning of belief and supports a revision of a strict demarcation between standard and non-standard beliefs. (shrink)

“Experimental jurisprudence” draws on empirical data to inform questions typically associated with jurisprudence or legal theory. Scholars in this flourishing movement conduct empirical studies about a variety of legal language and concepts. Despite the movement’s growth, its justification is still opaque. Jurisprudence is the study of deep and longstanding theoretical questions about law’s nature, but “experimental jurisprudence,” it might seem, simply surveys laypeople. This Article elaborates and defends experimental jurisprudence. Experimental jurisprudence, appropriately understood, is not only consistent with traditional jurisprudence; (...) it is an essential branch of it. (shrink)

It is widely held that agent-neutral consequentialism is incompatible with deontic constraints. Recently, Kieran Setiya has challenged this orthodoxy by presenting a form of agent-neutral consequentialism that he claims can capture deontic constraints. In this reply, we argue against Setiya's proposal by pointing to features of deontic constraints that his account fails to capture.

This paper attempts to fill an epistemological gap in our theorizing about love with a sketch of an epistemology of love that unfolds by addressing Whitney Houston’s famous epistemological questions pertaining to how we can know whether another loves us. After arguing for three possible sources of the knowledge of love, it offers initial answers to how the knowledge of the presence or absence of another’s love can be acquired from the relevant possible sources previously established. These initial answers, though, (...) are unsatisfying because they invite more difficult questions that are then addressed, such as those pertaining to the kinds of things that constitute love’s expressions along with how to detect these expressions given the possibility of false positives. Addressing these questions ultimately leads to a sharpened, Aristotle-inspired account of how to acquire the knowledge of the presence or absence of another’s love by inferring it, respectively, from the successful or failed detection of love’s expressions.

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

In this article, robust evidence is provided showing that an individual’s moral character can contribute to the aesthetic quality of their appearance, as well as being beautiful or ugly itself. It is argued that this evidence supports two main conclusions. First, moral beauty and ugliness reside on the inside, and beauty and ugliness are not perception-dependent as a result; and, second, aesthetic perception is affected by moral information, and thus moral beauty and ugliness are on the outside as well.

Most philosophers have largely downplayed any relevance of multiple meanings of the folk concept of truth in the empirical domain. However, confusions about what truth is have surged in political and everyday discourse. In order to resolve these confusions, we argue that we need a more accurate picture of how the term ‘true’ is in fact used. Our experimental studies reveal that the use of ‘true’ shows substantial variance within the empirical domain, indicating that ‘true’ is ambiguous between a correspondence (...) and a coherence reading. We then explore the consequences of these results for the project of re-engineering truth. (shrink)

The Lockean Thesis says that you must believe p iff you’re sufficiently confident of it. On some versions, the 'must' asserts a metaphysical connection; on others, it asserts a normative one. On some versions, 'sufficiently confident' refers to a fixed threshold of credence; on others, it varies with proposition and context. Claim: the Lockean Thesis follows from epistemic utility theory—the view that rational requirements are constrained by the norm to promote accuracy. Different versions of this theory generate different versions of (...) Lockeanism; moreover, a plausible version of epistemic utility theory meshes with natural language considerations, yielding a new Lockean picture that helps to model and explain the role of beliefs in inquiry and conversation. Your beliefs are your best guesses in response to the epistemic priorities of your context. Upshot: we have a new approach to the epistemology and semantics of belief. And it has teeth. It implies that the role of beliefs is fundamentally different than many have thought, and in fact supports a metaphysical reduction of belief to credence. (shrink)

Phineas Gage’s story is typically offered as a paradigm example supporting the view that part of what matters for personal identity is a certain magnitude of similarity between earlier and later individuals. Yet, reconsidering a slight variant of Phineas Gage’s story indicates that it is not just magnitude of similarity, but also the direction of change that affects personal identity judgments; in some cases, changes for the worse are more seen as identity-severing than changes for the better of comparable magnitude. (...) Ironically, thinking carefully about Phineas Gage’s story tells against the thesis it is typically taken to support. (shrink)

When are morally good actions beautiful, when indeed they are? In this paper, it is argued that morally good actions are beautiful when they appear to express the deep or true self, and in turn tend to give rise to an emotion which is characterised by feelings of being moved, unity, inspiration, and meaningfulness, inter alia. In advancing the case for this claim, it is revealed that there are additional sources of well-formedness in play in the context of moral beauty (...) in addition to those that have tended to be focused on to date: one which is connected to imagining a deep location for the goodness concerned, and another which is connected to imagining that the goodness stems from capacities which are essential to the person.

What is the nature of the concept BEAUTY? Does it differ fundamentally from nearby concepts such as PRETTINESS? It is argued that BEAUTY, but not PRETTINESS, is a dual-character concept. Across a number of contexts, it is proposed that BEAUTY has a descriptive sense that is characterised by, inter alia, having intrinsically pleasing appearances; and a normative sense associated with deeply-held values. This account is supported across two, pre-registered, studies (N=500), and by drawing on analysis of corpus data. It is (...) suggested that this can help to explain why beauty, unlike prettiness, is thought to be deep in both the sense of being important, and in the sense of being less closely tied to sensory surfaces.

Which traits are beautiful? And is their beauty perceptual? It is argued that moral virtues are partly beautiful to the extent that they tend to give rise to a certain emotion— ecstasy—and that compassion tends to be more beautiful than fair-mindedness because it tends to give rise to this emotion to a greater extent. It is then argued, on the basis that emotions are best thought of as a special, evaluative, kind of perception, that this argument suggests that moral virtues (...) are partly beautiful to the extent that they tend to give rise to a certain kind of evaluative perceptual experience.

Colleagues are not only an integral part of many people’s lives; empirical research suggests that having a good relationship with one’s colleagues is the single most important factor for being happy at work. However, so far, no one has provided a comprehensive account of what it means to be a colleague. To address this lacuna, we have conducted both an empirical as well as theoretical investigation into the content and structure of the concept ‘colleague.’ Based on the empirical evidence that (...) we present in this paper, we argue that ‘colleague’ is a dual character concept that has both a descriptive and a normative basis for categorization. Its descriptive dimension is characterized by three features, according to which two people are colleagues if they work for the same institution and know each other, or if they work for the same institution and work in the same field. An independent normative dimension is revealed, which shows that, as colleagues, we are expected to fulfill substantial normative expectations. Understanding the expectations that are encoded in the very structure of this concept is crucial to lay the groundwork for an ethics of collegiality. (shrink)

Willful ignorance is an important concept in criminal law and jurisprudence, though it has not received much discussion in philosophy. When it is mentioned, however, it is regularly assumed to be a kind of self-deception. In this article I will argue that self-deception and willful ignorance are distinct psychological kinds. First, some examples of willful ignorance are presented and discussed, and an analysis of the phenomenon is developed. Then it is shown that current theories of self-deception give no support to (...) the idea that willful ignorance is a kind of self-deception. Afterwards an independent argument is adduced for excluding willful ignorance from this category. The crucial differences between the two phenomena are explored, as are the reasons why they are so easily conflated. (shrink)

An “inferentialist” semantic theory for some language L aims to account for the meanings of the sentences of L solely in terms of the inferential rules governing their use. A “hyper-inferentialist” theory admits into the semantics only “narrowly inferential” rules that normatively relate sentences of L to other sentences of L. A “strong inferentialist” theory also admits into the semantics “broadly inferential” rules that normatively relate perceptual states to sentences of L or sentences of L to intentional actions. It is (...) widely thought that only the latter of these two sorts of semantic theories is at all viable. I argue here that the opposite is so. Negatively, strong inferentialism is viciously circular: including rules into the semantic theory that relate perceptual states to sentences of the language requires us to appeal, in individuating those perceptual states, to the very meanings for which we are supposed to be inferentially accounting. Hyper-inferentialism does not face this problem because it does not appeal to any nonlinguistic states. Positively, though hyper-inferentialism is widely thought to be a theoretical non-starter, I argue here that it is a genuine theoretical possibility insofar as it essentially includes cross-perspectival inferences, inferences along the lines of the one from the sentences “The ball is in front of n,” “The ball is red,” and “The lighting is good” to the sentence “n sees that the ball is red.” I make the further exegetical claim that Robert Brandom, though unanimously taken to be a strong inferentialist, is in fact a hyper-inferentialist.

Why are moral actions beautiful, when indeed they are? This paper assesses the view, found most notably in Schiller, that moral actions are beautiful just when they present the appearance of freedom by appearing to be the result of internal harmony (the Schillerian Internal Harmony Thesis). I argue that while this thesis can accommodate some of the beauty involved in contrasts of the ‘continent’ and the ‘fully’ virtuous, it cannot account for all of the beauty in such contrasts, and so (...) needs to be weakened considerably (to the Internal Harmony Thesis). To account for the remaining beauty that cannot be fully accommodated even by this revised thesis, as well as the beauty contained in contrasts that involve agents who experience internal conflict as a result of being sensitive to different sources of moral value to an appropriate extent, a number of further theses need to be posited: namely, that the beauty of some moral actions is to be accommodated in terms of internal disharmony (the Internal Disharmony Thesis), and in terms of a felt harmony between the appreciator of the action and the executor of the action (the Affective Harmony Thesis). As such, in contrast to Schiller, I suggest that we need to take a pluralist and context-sensitive approach to accommodating the beauty of moral actions. (shrink)

The three young philosophers Kevin Mulligan, Peter Simons and Barry Smith have become well-known in the last few years especially in German-speaking analytical philosophy and phenomenology circles. This is on the one hand as a result of their historical and systematic philosophical work; but it is also because of the provocative way in which they represent their philosophy. Because they often appear in threes, they have become known as the "gang of three" or "three musketeers" or even – and (...) this in an admiring sense – "mafiosi" (Rescher). They are known primarily for the small workshops they have been organizing in uncomplicated Anglo-Saxon manner all over Europe. Their goal has been to show that analytic philosophy as it has been pursued up to now is in need of reform and also that the history of scientific philosophizing is not identical to the history of Anglo-Saxon analytic philosophy. Above all, they have tried to make more well known the Austrian tradition of scientific philosophy, and they can be given credit for having done much to promote the current interest in this tradition, which means: the history of Austrian philosophy of the 19th and early 20th centuries and its historical context in the Austro-Hungarian Empire.

I argue that the main existing accounts of the relationship between the beauty of environmental entities and their moral standing are mistaken in important ways. Beauty does not, as has been suggested by optimists, confer intrinsic moral standing. Nor is it the case, as has been suggested by pessimists, that beauty at best provides an anthropocentric source of moral standing that is commensurate with other sources of pleasure. I present arguments and evidence that show that the appreciation of beauty tends (...) to cause a transformational state of mind that is more valuable than mere pleasure, but that leads us to falsely represent beautiful entities as being sentient and, in turn, as having intrinsic moral standing. To this extent, beauty is not, then, a source of intrinsic moral standing; it’s a source of a more important anthropocentric value than has hitherto been acknowledged. (shrink)

ABSTRACTAndrew Bacon, Matti Eklund, and Patrick Greenough have individually proposed objections to the project in my book, Replacing Truth. Briefly, the book outlines a conceptual engineering project – our defective concept of truth is replaced for certain purposes with a team of concepts that can do some of the jobs we thought truth could do. Here, I respond to their objections and develop the views expressed in Replacing Truth in various ways.

This paper is a defense of moral evidentialism, the view that we have a moral obligation to form the doxastic attitude that is best supported by our evidence. I will argue that two popular arguments against moral evidentialism are weak. I will also argue that our commitments to the moral evaluation of actions require us to take doxastic obligations seriously.

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and (...) ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).

This book aims to develop certain aspects of Gottlob Frege’s theory of meaning, especially those relevant to intensional logic. It offers a new interpretation of the nature of senses, and attempts to devise a logical calculus for the theory of sense and reference that captures as closely as possible the views of the historical Frege. (The approach is contrasted with the less historically-minded Logic of Sense and Denotation of Alonzo Church.) Comparisons of Frege’s theory with those of Russell and others (...) are given. It is in the end shown that developing Frege’s theory in these ways reveals serious problems hitherto largely unnoticed, including those possibly rendering a Fregean intensional logic inconsistent even if his naïve class theory is excluded.

Perception is a central means by which we come to represent and be aware of particulars in the world. I argue that an adequate account of perception must distinguish between what one perceives and what one's perceptual experience is of or about. Through capacities for visual completion, one can be visually aware of particular parts of a scene that one nevertheless does not see. Seeing corresponds to a basic, but not exhaustive, way in which one can be visually aware of (...) an item. I discuss how the relation between seeing and visual awareness should be explicated within a representational account of the mind. Visual awareness of an item involves a primitive kind of reference: one is visually aware of an item when one's visual perceptual state succeeds in referring to that particular item and functions to represent it accurately. Seeing, by contrast, requires more than successful visual reference. Seeing depends additionally on meta-semantic facts about how visual reference happens to be fixed. The notions of seeing and of visual reference are both indispensable to an account of perception, but they are to be characterized at different levels of representational explanation. (shrink)

Perception involves the processing of content or information about the world. In what form is this content represented? I argue that perception is widely compositional. The perceptual system represents many stimulus features (including shape, orientation, and motion) in terms of combinations of other features (such as shape parts, slant and tilt, common and residual motion vectors). But compositionality can take a variety of forms. The ways in which perceptual representations compose are markedly different from the ways in which sentences or (...) thoughts are thought to be composed. I suggest that the thesis that perception is compositional is not itself a concrete hypothesis with specific predictions; rather it affords a productive framework for developing and evaluating specific empirical hypotheses about the form and content of perceptual representations. The question is not just whether perception is compositional, but how. Answering this latter question can provide fundamental insights into perception. (shrink)

Generic statements (‘Tigers have stripes’) are pervasive and developmentally early-emerging modes of generalization with a distinctive linguistic profile. Previous experimental work suggests that generics display a unique asymmetry between the prevalence levels required to accept them and the prevalence levels typically implied by their use. This asymmetry effect is thought to have serious social consequences: if speakers use socially problematic generics based on prevalence levels that are systematically lower than what is typically inferred by their recipients, then using generics will (...) likely exacerbate social stereotypes and biases. This paper presents evidence against the popular hypothesis that this asymmetry effect is unique to generics. Correcting for various shortcomings of previous studies, we found a generalized asymmetry effect across generics and various kinds of explicitly quantified statements (‘most’, ‘some’, ‘typically’, ‘usually’). In addition, to better understand the conditions under which generalized asymmetry effects may exacerbate biases, we examine whether speakers choose generalizing sentences based simply on their acceptance conditions, or are systematically sensitive to the implications likely drawn by their typical recipients. In support of the latter view, we found that, in neutral or cooperative scenarios, speakers reliably choose generalizing sentences whose implied prevalence levels closely match the actual ones. In non-cooperative scenarios, speakers exploit asymmetry effects to further their own goals by choosing generalizing sentences that are strictly true but likely to mislead their recipients. These results refine our understanding of the source of asymmetry effects and the conditions under which they may introduce biased beliefs into social networks. (shrink)

In this article, I present a novel argument against abortion. In short, what makes it wrong to kill someone is that they are a counterfactual person; counterfactual persons are individuals such that, were they not killed, they would have been persons. My view accommodates two intuitions which many views concerning the wrongness of killing fail to account for: embryo rescue cases and the impermissibility of infanticide. The view avoids embryo rescue cases because embryos in the rescue scenarios are not counterfactual (...) people: they are not counterfactual people because it is false to say that, were they not killed, they would have been persons. As a result, it does not follow from my account that there is a prohibition against allowing embryos to die. On the other hand, infants are counterfactual people: an infant is an individual such that, were she not killed, she would have been a person. (shrink)

This is a review article on Franz Brentano’s Descriptive Psychology published in 1982. We provide a detailed exposition of Brentano’s work on this topic, focusing on the unity of consciousness, the modes of connection and the types of part, including separable parts, distinctive parts, logical parts and what Brentano calls modificational quasi-parts. We also deal with Brentano’s account of the objects of sensation and the experience of time.

KK is the thesis that if you can know p, you can know that you can know p. Though it’s unpopular, a flurry of considerations has recently emerged in its favour. Here we add fuel to the fire: standard resources allow us to show that any failure of KK will lead to the knowability and assertability of abominable indicative conditionals of the form ‘If I don’t know it, p’. Such conditionals are manifestly not assertable—a fact that KK defenders can easily (...) explain. I survey a variety of KK-denying responses and find them wanting. Those who object to the knowability of such conditionals must either deny the possibility of harmony between knowledge and belief, or deny well-supported connections between conditional and unconditional attitudes. Meanwhile, those who grant knowability owe us an explanation of such conditionals’ unassertability—yet no successful explanations are on offer. Upshot: we have new evidence for KK. (shrink)

A realist theory of truth for a class of sentences holds that there are entities in virtue of which these sentences are true or false. We call such entities ‘truthmakers’ and contend that those for a wide range of sentences about the real world are moments (dependent particulars). Since moments are unfamiliar, we provide a definition and a brief philosophical history, anchoring them in our ontology by showing that they are objects of perception. The core of our theory is the (...) account of truthmaking for atomic sentences, in which we expose a pervasive ‘dogma of logical form’, which says that atomic sentences cannot have more than one truthmaker. In contrast to this, we uphold the mutual independence of logical and ontological complexity, and the authors outline formal principles of truthmaking taking account of both kinds of complexity.

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Although this thought experiment was originally introduced to illuminate questions in the theory of reference, it has also played a crucial role in empirically informed debates within the philosophy of psychology about people’s ordinary natural kind concepts. Those debates have sought to accommodate (...) an apparent fact about ordinary people’s judgments: Intuitively, the Twin Earth liquid is not water. We present results from four experiments showing that people do not, in fact, have this intuition. Instead, people tend to have the intuition that there is a sense in which the liquid is not water but also a sense in which it is water. We explore the implications of this finding for debates about theories of natural kind concepts, arguing that it supports views positing two distinct criteria for membership in natural kind categories – one based on deeper causal properties, the other based on superficial, observable properties.

DNA sequencers, Twitter, MRIs, Facebook, particle accelerators, Google Books, radio telescopes, Tumblr: what do these things have in common? According to the evangelists of “data science,” all of these are instruments for observing reality at unprecedentedly large scales and fine granularities. This perspective ignores the social reality of these very different technological systems, ignoring how they are made, how they work, and what they mean in favor of an exclusive focus on what they generate: Big Data. But no data, big (...) or small, can be interpreted without an understanding of the process that generated them. Statistical data science is applicable to systems that have been designed as scientific instruments, but is likely to lead to confusion when applied to systems that have not. In those cases, a historical inquiry is preferable. (shrink)

There are many things—call them ‘experts’—that you should defer to in forming your opinions. The trouble is, many experts are modest: they’re less than certain that they are worthy of deference. When this happens, the standard theories of deference break down: the most popular (“Reflection”-style) principles collapse to inconsistency, while their most popular (“New-Reflection”-style) variants allow you to defer to someone while regarding them as an anti-expert. We propose a middle way: deferring to someone involves preferring to make any decision (...) using their opinions instead of your own. In a slogan, deferring opinions is deferring decisions. Generalizing the proposal of Dorst (2020a), we first formulate a new principle that shows exactly how your opinions must relate to an expert’s for this to be so. We then build off the results of Levinstein (2019) and Campbell-Moore (2020) to show that this principle is also equivalent to the constraint that you must always expect the expert’s estimates to be more accurate than your own. Finally, we characterize the conditions an expert’s opinions must meet to be worthy of deference in this sense, showing how they sit naturally between the too-strong constraints of Reflection and the too-weak constraints of New Reflection.

While recently hyped as a defense against AI plagiarism, oral exams have fallen out of favor in American philosophy departments. They are often perceived as part of an antiquated system where the day-to-day coursework is sharply distinguished from a 100% weighted final exam, with a more oppositional than collaborative student-professor relationship. Such examinations do not lend themselves to blind grading, and also reinforce the existing privilege of students who are confident, fast-spoken, and know what to study. This kind of oral (...) examination is clearly at odds with the contemporary transparent and collaborative process embodied in techniques like specifications grading, with its proven benefits for novice philosophy students in introductory-level courses. I want to defend a rather different role for oral exams. Novice philosophy students need rapid feedback in order to know whether they have correctly understood the expectations embodied in syllabi and rubrics. Six best practices are offered for achieving this goal while minimizing drawbacks. (shrink)

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

Causal selection is the cognitive process through which one or more elements in a complex causal structure are singled out as actual causes of a certain effect. In this paper, we report on an experiment in which we investigated the role of moral and temporal factors in causal selection. Our results are as follows. First, when presented with a temporal chain in which two human agents perform the same action one after the other, subjects tend to judge the later agent (...) to be the actual cause. Second, the impact of temporal location on causal selection is almost canceled out if the later agent did not violate a norm while the former did. We argue that this is due to the impact that judgments of norm violation have on causal selection—even if the violated norm has nothing to do with the obtaining effect. Third, moral judgments about the effect influence causal selection even in the case in which agents could not have foreseen the effect and did not intend to bring it about. We discuss our findings in connection to recent theories of the role of moral judgment in causal reasoning, on the one hand, and to probabilistic models of temporal location, on the other. (shrink)

We argue that philosophers ought to distinguish epistemic decision theory and epistemology, in just the way ordinary decision theory is distinguished from ethics. Once one does this, the internalist arguments that motivate much of epistemic decision theory make sense, given specific interpretations of the formalism. Making this distinction also causes trouble for the principle called Propriety, which says, roughly, that the only acceptable epistemic utility functions make probabilistically coherent credence functions immodest. We cast doubt on this requirement, but then argue (...) that epistemic decision theorists should never have wanted such a strong principle in any case. (shrink)

Coronavirus disease 2019 can lead to respiratory failure. Some patients require extracorporeal membrane oxygenation support. During the current pandemic, health care resources in some cities have been overwhelmed, and doctors have faced complex decisions about resource allocation. We present a case in which a pediatric hospital caring for both children and adults seeks to establish guidelines for the use of extracorporeal membrane oxygenation if there are not enough resources to treat every patient. Experts in critical care, end-of-life care, bioethics, and (...) health policy discuss if age should guide rationing decisions. (shrink)

Let’s say that you regard two things as on a par when you don’t prefer one to other and aren’t indifferent between them. What does rationality require of you when choosing between risky options whose outcomes you regard as on a par? According to Prospectism, you are required to choose the option with the best prospects, where an option’s prospects is a probability-distribution over its potential outcomes. In this paper, I argue that Prospectism violates a dominance principle—which I call The (...) Principle of Predominance—because it sometimes requires you to do something that’s no better than the alternatives and might be worse. I argue that this undermines the strongest argument that’s been given in favor of Prospectism. (shrink)

Of the dozens of purported solutions to the liar paradox published in the past fifty years, the vast majority are "traditional" in the sense that they reject one of the premises or inference rules that are used to derive the paradoxical conclusion. Over the years, however, several philosophers have developed an alternative to the traditional approaches; according to them, our very competence with the concept of truth leads us to accept that the reasoning used to derive the paradox is sound. (...) That is, our conceptual competence leads us into inconsistency. I call this alternative the inconsistency approach to the liar. Although this approach has many positive features, I argue that several of the well-developed versions of it that have appeared recently are unacceptable. In particular, they do not recognize that if truth is an inconsistent concept, then we should replace it with new concepts that do the work of truth without giving rise to paradoxes. I outline an inconsistency approach to the liar paradox that satisfies this condition. (shrink)
